# Trailmark Summary

Runs `trailmark analyze --language auto --summary` on a target directory.

## When to Use

- Vivisect Phase 0 needs a quick structural overview before decomposition
- Galvanize Phase 1 needs detected languages and entry point count
- Quick orientation on an unfamiliar codebase before deeper analysis

## When NOT to Use

- Full structural analysis with all passes needed (use `trailmark-structural`)
- Detailed code graph queries (use the main `trailmark` skill directly)
- You need hotspot scores or taint data (use `trailmark-structural`)

## Rationalizations to Reject

| Rationalization | Why It's Wrong | Required Action |
|-----------------|----------------|-----------------|
| "I can read the code manually instead" | Manual reading misses parser-based language detection, dependency data, and entry point enumeration | Install and run trailmark |
| "Language detection doesn't matter" | Wrong language selection produces empty or partial analysis | Use Trailmark's parser-based detection or `--language auto` |
